Abstract

A magnetic recording and reproducing apparatus of the cassette type having a tape drive system in which a tape supply reel and a take-up reel are accommodated in a juxtaposed or unitarily stacked relation in a detachable tape cassette and movable tape guide rollers or pins are provided so that a magnetic tape can substantially straightly run in the quick feed and quick rewinding operation without being interfered by a rotary video head and other members, while the tape can be brought into engagement with the rotary video head in the recording and reproducing operation.

Claims

1. A magnetic video recording and reproducing apparatus, comprising:

a main body member;

a tape cassette detachably mounted on said main body member and having a cassette body, at least one elongated cut-out portion formed on one side of said cassette body and extending inwardly of said side from one edge portion thereof, and at least one face portion extending from said one edge portion substantially at right angles to the plane of said one side, said face portion having at least one opening therein;

a tape supply reel and take-up reel housed in said cassette body for carrying a magnetic tape;

a plurality of first tape guides mounted in said cassette body, said magnetic tape being trained at least partially around said first tape guides, wherein the portion of said magnetic tape which extends between first and second of said first tape guides is disposed adjacent to said at least one opening in said face portion;

means for engaging with and holding said cassette on said main body member;

tape driving means, including a pinch roller and a capstan for operatively engaging said magnetic tape;

a plurality of slidably movable second tape guides mounted on said main body member, slidably movable between first and second positions, wherein in said first position, said second tape guides extend into said cassette body through said at least one elongated cut-out portion such that said magnetic tape is disposed between said second guides and said at least one opening in said face portion;

first and second stationary magnetic head means mounted on said main body member;

a cylindrical tape guide disposed on said main body member externally of said cassette body; and

rotating magnetic head means disposed on said cylindrical tape guide;

wherein, in said second position, said second tape guides are disposed externally of said cassette body adjacent said cylindrical tape guide such that said magnetic tape portion extending between said first and second first tape guides extends out of said cassette body through said at least one opening, said magnetic tape portion being further trained at least partially around said slidably movable second tape guides and said cylindrical tape guide, said magnetic tape operatively engaging said first and second stationary magnetic head meAns and said rotating magnetic head means.

2. The apparatus according to claim 1, further comprising operating means operatively connected with said movable second tape guides and moving substantially parallel thereto.

3. The apparatus according to claim 1, further comprising:

a further opening defined in said one side of said cassette body; and

a still further opening in said one face portion;

wherein when said cassette is engaged with said main body member, said capstan extends into said cassette body through said further opening and said pinch roller extends into said cassette body through said still further opening, said magnetic tape being disposed between said capstan and said pinch roller and operatively engaged therewith inside said cassette body at least in said second position of said second tape guides.

4. A magnetic video recording and reproducing apparatus according to claim 1, in which the central axis of said cylindrical tape guide is inclined with respect to the central axes of said tape supply reel and take-up reel.

5. A magnetic video recording and reproducing apparatus, comprising:

a main body member;

a tape cassette detachably mounted on said main body member and having;

a cassette body, and at least one cut-out portion formed in the base portion of said cassette body and extending inwardly from one edge portion thereof;

a tape supply reel and take-up reel housed in said cassette body for carrying a magnetic tape;

a plurality of first slidably movable tape guides mounted in said cassette body and slidably movable between first and second positions, said magnetic tape being trained at least partially around said first tape guides;

tape driving means, including a pinch roller, slidably movable between first and second positions, and a capstan operatively engageable with said magnetic tape;

a plurality of second slidably movable tape guides mounted on said main body member and slidably movable between first and second positions, wherein, in said first position, said second tape guides are held out of engagement with said magnetic tape;

at least one stationary magnetic head means disposed on said main body member;

a cylindrical tape guide disposed on said main body member;

rotating magnetic head means disposed on said cylindrical guide; and

means slidably moving said first and second tape guides and said pinch roller from said first positions into said second positions wherein said second tape guides and said pinch roller are disposed in operative engagement with said magnetic tape internally of said cassette body, said second tape guides being disposed adjacent said cylindrical guide such that a portion of said magnetic tape extending between first and second of said first tape guides is further trained at least partially around said second tape guides and said cylindrical guide, said magnetic tape operatively engaging said stationary magnetic head means and said rotating head means.

6. The apparatus according to claim 5, wherein said second movable tape guides are movable between said first and second positions in parallel relationship to each other and on opposite sides of said cylindrical tape guide and wherein said second position of said second tape guides is disposed nearer said cylindrical tape guide than said first position of said second tape guide.

7. The apparatus according to claim 5, further comprising means normally biasing said first movable tape guides in the direction of said first position of said first movable tape guides.

8. The apparatus according to claim 5, wherein said cylindrical tape guide is vertically movable between a first position internally of said cassette body and a second position externally of said cassette body and internally of said main body member.
